Each of my stones is handcut by me and highly polished on both sides with smooth edging on the bottom for easy setting.

Formed millions of years ago, Thunderegg (Thunder egg) is a round nodule-like rock formation, filled with agate, jasper, opal, and/or quartz crystals. Thunderegg is also called agate-filled or jasper-filled nodules. Typically, the size is from two to six inches in diameter. Rarely eggs can be one to three feet long and weigh over a ton. Some specimens contain two or three eggs connected together.

The exterior surface is white-gray to reddish-brown, looks rough and unattractive but the inner content may surprise you with its impressive crystal formation and colorful mineral patterns.

The name was given according to an old legend of the Warm Springs Indians. Two neighboring snow-capped picks - Mount Jefferson and Mount Hood got angry with each other and threw eggs of Thunderbirds which were nestled in both mountains. "Thunder spirits of the mountains who lived in the craters hurled the nodules to the accompaniment of much lightning and thunder".
